 Madagascar and Comoro parrots, however, are

 this group of islands there should be three such 

 dull-coloured species belonging to genera noted 

 for their bright-coloured species. Possibly this 

 is the effect of isolation for a very great time, 

 and these birds may be the oldest members of 

 the avifauna of the Seychelles.^ 



During the night spent at Cascade Estate I

 Thommasset informed me he frequently heard, 

 and occasionally saw as it flew by day when
